4 pin circular plug on M50 engine, what is it please??

[e30-EVN]

Just had my M50 lump delivered and I can't figure out what the plug is for!
It comes out from the loom near starter and is similar to the bottom injector plug on an M20 but there is nowhere for it to plug into, its round and 4 pin with a threaded plastic surround. Can any1 tell me what its for? I'm thinkin the lambda sensor but I could be wrong.

I would guess at a lambda sensor.

[RichIS]

is it not the maf sensor plug ?

[e30-EVN]

No its similar to that but it comes out from near the starter

[Cook318IS]

sounds like the lambda to me.

Bit off topic but i dont suppose your down in devon atm with silver facelift e30 with a private plate like your username?

I think they are the same between vanos and non vanos - bmwfans.info seems to think so anyway. Anybody able to confirm? £40 posted? I think it cost me about £65-£70 (it was a while ago though )

[e30-EVN]

[DanThe]

Non vanos and vanos sensors are the same
